| Abstract: | The reliability analysis of static strength for space beam and plate structural system was proposed. The explicit expressions of safe margin and the sensitivity of safe margin to every random variable were established by static strength theory of the structural system reliability and the stochastic finite element method. Thus, it is easy to calculate the relativity of safe margin and it is propitious to increase calculated precision and reform the reliability calculation method of the space beam and plate structural system. The calculation results of a numerical example indicate that the method is feasible and valid. |
